I bought these sheets for our  regularly used guest room with a queen bed. The sheets fit perfectly! We even have a 1.5" foam mattress on top of the regular mattress and the fitted sheet still is nice and snug but not overly stretched. The blend is 55% polyester and 45% cotton which gives them a smooth and soft feeling AND the best part is they are not wrinkly after being washed and dried!!! Gone are the days of being embarrassed that my guests see my wrinkly sheets!
